3D movies, navigation, printers, and televisions are no strangers. Today, the operating room begins to stage "3D blockbuster"-Recently, Sun Yat-sen Memorial Hospital of Sun Yat-sen University carried out surgical operations under 3D vision, which not only retains the fine and minimally invasive characteristics of traditional laparoscopic surgery, but also has the advantages of high-definition stereoscopic vision, greatly Improve the accuracy of the operation.
Laparoscopic surgery is about to enter the 3D era
Wearing sunglasses for surgery? Is the doctor playing cool? This is doing 3D laparoscopic surgery, and its biggest advantage is to make the surgeon's vision clearer and more intuitive. "In the 3D field of view, my eyes can walk between various organs, one blood vessel and one silk can be seen clearly, and even nerve fibers can be seen, as if drilling into the patient's tummy, not only the feeling of being in person You can touch it to change it, it is more enjoyable than sitting in a movie theater and watching 3D blockbusters. "Professor Huang Jian, director of urology, described his first experience of 3D surgery.
The instrument helps the organs become three-dimensional
In recent decades, the main direction of surgical development is minimally invasive laparoscopic surgery: no surgery is required, the doctor only needs to open a few "holes" in the patient, extend the laparoscope into it, and then transmit the image to the monitor, The doctor operated the instrument to complete the operation.
3D laparoscopy technology is developed on the basis of ordinary laparoscopy. Through the 3D high-definition laparoscope system, the images transmitted by the laparoscope are combined into a three-dimensional effect by two cameras. The doctor must wear 3D glasses to perform the operation. "When I first put on the 3D glasses, the eyes have a process of focusing. When the brain matches the left and right eyes together, a 3D image is formed in our eyes, and the internal organs we see are three-dimensional." Huang Jian said.
Suitable for fine surgery with deep involvement
Huang Jian believes that 3D surgery is the future development direction of surgery, and is suitable for all kinds of laparoscopic surgery, especially for laparoscopic surgery in urology. "There is an important feature of urological diseases: the organs are very deep, so we are dubbed as" hole experts "," he said that the deep places are best for 3D laparoscopy, urological surgery for bladder cancer radical surgery, Urinary tract reconstruction surgery, radical prostate cancer surgery, nephrectomy surgery, and ureter replantation surgery are all suitable for 3D laparoscopy.
"Maximizing the accuracy of surgery is the highest level that surgeons pursue." Huang Jian said that 3D laparoscopy allows the image to be three-dimensional, which facilitates the removal of the lesion without "injuring innocent people." The organs of the urinary system are often "implicated". For example, bladder cancer and prostate cancer are the first and second tumors in the urogenital system in China, and can be radically excised. However, there are many nerves (such as erectile nerves) and blood vessels around the bladder and prostate, which affects urine control and sexual function. This requires precise surgery, otherwise, the nerves will be cut off with a knife, and the function will be lost. "The urology department of the hospital began to perform 3D laparoscopic surgery for a group of patients at the end of November last year. The effect is more ideal than other surgical methods.
The piezoelectric buzzers (for Driver Circuit Built-in) offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a Piezo Buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous for any battery operated device. Since piezo buzzers don`t have a magnet in their construction, it eliminates EMI/EMC issues.
